Christos Margiolis 3d44dce90a sort: test against all month formats in month-sort ... The CLDR specification [1] defines three possible month formats: - Abbreviation (e.g Jan, Ιαν) - Full (e.g January, Ιανουαρίου) - Standalone (e.g January, Ιανουάριος) Many languages use different case endings depending on whether the month is referenced as a standalone word (nominative case), or in date context (genitive, partitive, etc.). sort(1)'s -M option currently sorts months by testing input against only the abbrevation format, which is essentially a substring of the full format. While this works fine for languages like English, where there are no cases, for languages where there is a different case ending between the abbreviation/full and standalone formats, it is not sufficient. For example, in Greek, "May" can take the following forms: Abbreviation: Μαΐ (genitive case) Full: Μαΐου (genitive case) Standalone: Μάιος (nominative case) If we use the standalone format in Greek, sort(1) will not able to match "Μαΐ" to "Μάιος" and the sort will fail. This change makes sort(1) test against all three formats. It also works when the input contains mixed formats.
